The BFEs on the Preliminary FIRMs are referenced in a vertical datum called North American Vertical Datum of 1988 (NAVD 88). ABFE information does NOT affect Federal flood insurance rating or requirements. The Base Flood Elevation (BFE) on FEMA’s FIRMs and PFIRMs is a measurement of height above a fixed point in the ground, not a measurement of flood height above the level of the ground at your property. (Note: only effective FIRM and coastal Advisory Base Flood Elevation (ABFE) information are available for this county.

Online tutorials are available from FEMA to provide assistance. For some communities, revised preliminary FIRM information has been released and is incorporated into the viewing options listed below. Users can look up property-specific information using the “What Is My Base Flood Elevation (BFE)?” Address Lookup Tool, use the community map viewers listed below (see the Preliminary FIRM Viewer User Guide), or get PDF map panels, Flood Insurance Study (FIS) reports, and GIS data via FEMA’s Flood Map Service Center. ![]() The approximate two-mile grid of control across Jefferson County (less in the urban core of Louisville) are tied to the NGS High Accuracy Reference Network (HARN).Preliminary and revised preliminary Flood Insurance Rate Map (FIRM) information is made available through this page as it is released. The monuments are recovered at least every five years. All are permanent disks, most set in 40" concrete columns, and all have a stability rating of A or B as defined by the National Geodetic Survey (NGS). Address Lookup Tool, use the community map viewers listed below (see the Preliminary FIRM Viewer User Guide ), or get PDF map panels, Flood Insurance Study (FIS) reports, and GIS data via FEMA’s Flood Map Service Center. LOJIC has installed and annually maintains the first order horizontal/vertical geodetic control monuments in a county-wide network of control monuments. Users can look up property-specific information using the What Is My Base Flood Elevation (BFE). ![]() The network was established in 2001 by the Louisville/Jefferson County Information Consortium (LOJIC). The Jefferson County, Kentucky geodetic control network consists of a county-wide, locally maintained grid of first-order geodetic survey control monuments. To request a Base Flood Elevation Letter for your property, click the "BFE Letter" Icon MSD also regulates to the local regulatory base flood elevation and the combined sewer floodprone base flood elevation if a project is impacted by the local regulatory floodplain or the combined sewer floodprone area. The FEMA BFE was adopted by the National Flood Insurance Program as the basis for floodplain management and flood insurance regulations. The Base Flood Elevation, or BFE, is the height of the base (1-percent-annual-chance) flood, in feet, in relation to the North American Vertical Datum of 1988. As the Official Map Repository of the Jefferson County, Kentucky Flood Insurance Rate Maps (FIRM), MSD can assist surveyors in acquiring Base Flood Elevations for properties within Jefferson County.
